A2Z Garage Doors
Most homeowners never think about their garage door until something stops working. But the real problem usually starts small, with weather stripping that's cracked, compressed, or missing entirely. After 15 years on service calls across Corona and Riverside County, I've seen how a $50 seal issue turns into a $500 energy bill problem in just one season.
Weather stripping and seals are the unsung heroes of your garage. They keep dust, insects, and outdoor air from leaking into your home. When they fail, your HVAC system works overtime. Your electric bill climbs. And you lose the climate control you paid for. The good news: catching this early is simple, and the fix costs far less than ignoring it.
Look at the bottom seal of your garage door right now. If it's cracked, flattened, or pulling away from the frame, it's time to act. A healthy bottom seal should feel firm and create a tight contact with your concrete floor. If you can slip a sheet of paper under it easily, the seal has lost its compression.
Check the threshold pan too. This is the piece that sits at the base of your door opening. Over Corona's hot, dry summers and occasional rain events, these deteriorate faster than most homeowners realize. Cracks in the threshold trap water and debris. That moisture then works its way into your concrete and walls.
Another sign: drafts. If you feel air movement around your door frame on a calm day, the side seals are compromised. In winter months, this creates a noticeable temperature drop inside your garage and the attached home. Summer heat bleed is just as costly.
Corona sits in a semi-arid zone with temperature swings and intense UV exposure. Our summers regularly hit 105°F. This heat causes rubber and foam seals to harden and lose elasticity. They crack rather than flex. Winter rains, while occasional, expose seals to moisture cycles that speed degradation.
If you have an older door, the seals are likely original equipment. Most rubber and foam bottom seals last 5 to 7 years under normal conditions. In our climate, expect closer to 4 to 6 years.

The bottom seal takes the most abuse. It bears weight, absorbs temperature swings, and compresses under your door's movement. Replace it every 4 to 6 years, or immediately if you see visible cracks.
Side seals (the vertical strips on your door frame) typically last longer because they're not weight-bearing. However, if you notice a draft or visible gaps, don't wait. The cost of replacement is minimal compared to the energy waste.
The threshold seal runs horizontally at the base of your opening frame. This one gets hit by moisture from below and debris from outside. If your concrete around the threshold is cracked or uneven, the seal won't seat properly no matter how new it is. We often recommend addressing concrete damage before replacing a seal, or it'll fail again quickly.
Top seals are often overlooked. They prevent drafts at the top of your door opening. Inspect them during your monthly maintenance routine. A failing top seal can pull your heating or cooling directly outside.
Our garage door maintenance guide for Corona homeowners covers inspection frequency in detail. It's worth a quick read if you're not checking seals monthly already.
Weather stripping and seal replacement isn't expensive. A bottom seal runs $50 to $150 in materials. Labor typically adds another $100 to $200. Full threshold replacement with seal might run $300 to $500. Compare that to a single month of wasted cooling or heating energy, and the ROI is immediate.

Many homeowners pair seal replacement with routine garage door lubrication and maintenance. These two tasks together prevent 80 percent of operational issues we see.
A silent draft today becomes an energy bill crisis tomorrow. The longer you wait, the more secondary damage occurs. Moisture enters where it shouldn't. Your garage temperature drifts further from your home's conditioned space. Small cracks in seals grow larger.
If you're noticing gaps, drafts, or visible cracks in your door's weather stripping, don't delay. Call us at 951-554-5737 or contact Garage Door Corona online to schedule your inspection. We'll give you an honest assessment and a straightforward price.
Your garage door works hard in Corona's heat and sun. The seals protecting your investment deserve the same attention.
How long do garage door bottom seals last? In Corona's climate, expect 4 to 6 years. Harsh UV exposure and temperature swings accelerate breakdown compared to milder regions. Replace sooner if you see cracks or flattening.
Can I replace weather stripping myself? Yes, bottom and side seals are homeowner friendly. Measure twice, purchase the correct profile (your door's manual specifies this), and snap or slide the new seal into place. Threshold seals require more precision and sometimes concrete work.
What's the difference between a bottom seal and a threshold seal? The bottom seal attaches to your door and creates the seal when closed. The threshold is a permanent pan at your opening's base. Both work together. Either can fail independently.
Why is my garage suddenly drafty after years of being fine? Seals compress, crack, or pull free over time. Corona's heat accelerates this. If it's sudden, check for debris blocking the seal or concrete heave pushing the door out of alignment.
Does replacing seals reduce energy costs? Yes. A failing seal can add 10 to 15 percent to monthly heating and cooling costs for an attached garage. Replacement typically pays for itself in 1 to 2 months of energy savings.
